Overview
This HTS category, 3908.90.20.00, specifically covers copolymers of bis(4-amino-3-methylcyclohexyl)methane, isophthalic acid, and laurolactam in their primary forms. Primary forms, as defined in Chapter 39, generally refer to bulk materials such as powders, granules, flakes, lumps, and blocks, as well as liquids and pastes. These materials are intermediate products used in the manufacture of various plastic articles.
This classification distinguishes itself from its sibling category, 3908.90.70.00, which is designated for "Other" polyamides in primary forms that do not fit the specific composition described herein. Therefore, any polyamide copolymer not falling under the precise chemical description of bis(4-amino-3-methylcyclohexyl)methane-isophthalic acid-laurolactam copolymer would be classified under the "Other" category at this level.
As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification under 3908.90.20.00 is final based on the chemical composition of the polyamide copolymer. Practical classification relies on verifying the presence and relative proportions of bis(4-amino-3-methylcyclohexyl)methane, isophthalic acid, and laurolactam within the polymer structure to ensure accurate duty assessment.
